OBJECTIVE: This study aimed to do a systematic literature review addressing the importance of the analysis of physical functional performance for the construction of specific tools to support communication. METHODS: The review followed PRISMA guidelines. We searched articles from 2009 to 2021 using three databases (PubMed, Lilacs in Portuguese, and SciELO). Three reviewers extracted the data. Registration was made to PROSPERO. The risk of bias was assessed using the Cochrane Collaboration tool. RESULTS: We found 132 articles in the databases. First, we excluded 31 articles because they did not provide evidence for the use of alternative communication in people with CP and did not use high technology resources. We also excluded 57 duplicated articles. At the end of this first step, 44 articles were left, 38 of them were excluded because they are not clinical trials. We selected 6 articles for the final analysis. CONCLUSIONS: The systematic review had a positive impact on the precise dissemination of knowledge ensuring comparisons of interventions and articles such as assistive technology programs.","PeriodicalId":22201,"journal":{"name":"Technology and Disability","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47669007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

OBJECTIVE: The purpose of the study is to identify the most significant barriers to the usage of AT by children with specific learning disabilities and suggest various measures to deal with it. METHODS: To accomplish the study interviews were conducted with special education teachers of schools in India to find out the major barriers toward the utilisation of AT. First, Qualitative analysis was performed using CAQDAS tool QDA Miner Lite to identify the barriers towards effective utilisation of AT. Further, ISM technique and MICAMAC analysis were used to corroborate the most significant barriers. RESULTS: The results revealed the most significant barriers to implementation of AT and also that timely managing these major barriers can lower the effect on other barriers. CONCLUSION: Eliminating the significant barriers would enhance the use of AT by the special education teachers, parents, and children with SLDs. Effective use of AT can prove to be benediction in the times of pandemic.","PeriodicalId":22201,"journal":{"name":"Technology and Disability","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44361336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biswas","doi":"10.3233/tad-200292","DOIUrl":"https://doi.org/10.3233/tad-200292","url":null,"abstract":"BACKGROUND: Users with Severe Speech and Motor Impairment (SSMI) often use a communication chart through their eye gaze or limited hand movement and care takers interpret their communication intent. There is already significant research conducted to automate this communication through electronic means. Developing electronic user interface and interaction techniques for users with SSMI poses significant challenges as research on their ocular parameters found that such users suffer from Nystagmus and Strabismus limiting number of elements in a computer screen. This paper presents an optimized eye gaze controlled virtual keyboard for English language with an adaptive dwell time feature for users with SSMI. OBJECTIVE: Present an optimized eye gaze controlled English virtual keyboard that follows both static and dynamic adaptation process. The virtual keyboard can automatically adapt to reduce eye gaze movement distance and dwell time for selection and help users with SSMI type better without any intervention of an assistant. METHODS: Before designing the virtual keyboard, we undertook a pilot study to optimize screen region which would be most comfortable for SSMI users to operate. We then proposed an optimized two-level English virtual keyboard layout through Genetic algorithm using static adaptation process; followed by dynamic adaptation process which tracks users’ interaction and reduces dwell time based on a Markov model-based algorithm. Further, we integrated the virtual keyboard for a web-based interactive dashboard that visualizes real-time Covid data. RESULTS: Using our proposed virtual keyboard layout for English language, the average task completion time for users with SSMI was 39.44 seconds in adaptive condition and 29.52 seconds in non-adaptive condition. Overall typing speed was 16.9 lpm (letters per minute) for able-bodied users and 6.6 lpm for users with SSMI without using any word completion or prediction features. A case study with an elderly participant with SSMI found a typing speed of 2.70 wpm (words per minute) and 14.88 lpm (letters per minute) after 6 months of practice. CONCLUSIONS: With the proposed layout for English virtual keyboard, the adaptive system increased typing speed statistically significantly for able bodied users than a non-adaptive version while for 6 users with SSMI, task completion time reduced by 8.8% in adaptive version than nonadaptive one. Additionally, the proposed layout was successfully integrated to a web-based interactive visualization dashboard thereby making it accessible for users with SSMI.","PeriodicalId":22201,"journal":{"name":"Technology and Disability","volume":"1 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3233/tad-200292","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42385272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, companies tend to ignore a section of their customer base, i.e. those who are visually impaired; although there are well-established standards set by WCAG 2.0 (Web Content Accessibility Guidelines). Although most e-commerce companies in India conform to these guidelines, as per the recommendations from the Indian government; however ironically; these are not accessible by the blind. OBJECTIVE: This paper specially focuses on the list of problems that the visually-impaired in India face while trying to access e-commerce sites, as most of the sites haven’t conformed to the WCAG 2.0 guidelines. METHOD: Qualitative analysis through the Repertory technique by Kelly in which, the grid developed for different constructs addressing various problems faced by such users in accessing e-commerce websites. FINDINGS: From the findings, it is evident that these visually impaired people are extremely open to gaining access towards the companies’ strategies, as they also want to be a part of the main segment of the society, and would in turn be a strong contributor to the profits of the companies, if they’re taken seriously. The findings also have a series of managerial as well as social implications. CONCLUSION: Further, the study also looks at lending some suggestions through which, marketing managers would be able to look into this prevailing problem, and thereby address the same, while enhancing their level of engagement with this specially-enabled client base. This would result not only in adding profits to the business at large, but also ensure customer satisfaction and delight, albeit the fact that they’re differently abled.","PeriodicalId":22201,"journal":{"name":"Technology and Disability","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3233/TAD-200293","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49365959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Floros","doi":"10.3233/TAD-200326","DOIUrl":"https://doi.org/10.3233/TAD-200326","url":null,"abstract":"BACKGROUND: One of the most serious concerns of parents, caregivers, teachers and therapists is children’s independent living, particularly of those with special educational needs (SEN). Purpose-built programs for the acquisition of independent living skills are considered a priority in special education settings. The main problem is the inefficacy of detached interventions to meet the needs of as many students as possible. OBJECTIVE: Our response is to create transmedia applications for inclusive learning environments. To this end, we have taken a participatory design approach to develop a project for Daily Living Skills Training by combining special education pedagogies, filmic methods, game design and innovative technologies. In this paper, we present the design and development of Waking up In the Morning (WUIM), and its improvement through user-based and expert-based evaluations by students, therapists and developers. The main research purpose is to confirm if: (1) the final products of the WUIM project could be educational resources for students with SEN and (2) the common gaming experience could promote collaborative learning, regardless of students’ cognitive profile. METHODS: During the alpha phase, we developed and improved WUIM. In July 2020, we implemented and evaluated WUIM in special education settings (beta-phase). More specifically, a quantitative and qualitative formative evaluation was conducted with children who have developmental disabilities (N= 11), their therapists (N= 7) and developers (N= 2). Methods of data collection included questionnaires filled in by therapists and developers, participant observation by researchers and interviews with children. RESULTS: The results of the formative evaluation were generally positive regarding four-factor groups that shape the learning experience: Content, Technical characteristics, User state of mind, Characteristics that allow learning. After the design team reviewed the potential users and experts’ comments that were mainly related to the user interface, the application was improved. CONCLUSIONS: The two hypotheses have been largely confirmed. Overall, we propose a simplified development process that showcases the importance of arts-based methods and aesthetics which deliver representational fidelity. The study reveals the necessity of developing transmedia learning materials to meet each individual’s needs.","PeriodicalId":22201,"journal":{"name":"Technology and Disability","volume":"1 1","pages":"1-26"},"PeriodicalIF":0.5,"publicationDate":"2021-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3233/TAD-200326","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43531633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is important for web developers to ensure that their website is accessible according to WCAG standards for people with different range of abilities. There is plethora of tools for ensuring conformance to WCAG standards but not many studies compared performance of automatic WCAG tools. OBJECTIVE: This paper compares a set of ten WCAG tools and their results in terms of ease of comprehension and interpretation by web developers. We proposed a Common User Profile format to help personalize contents of website making it accessible to people with different range of abilities. METHODS: We selected ten WCAG tools from World Wide Web Consortium (W3C) to evaluate landing pages of two popular websites. For each webpage, we identified accessibility issues and recommended alternate suggestions to help developers improve accessibility. Further, we highlighted accessibility issues that cannot be captured only through conformance to WCAG tools; and proposed additional methods to evaluate accessibility through an Inclusive User Model. We then demonstrated how simulation of user interaction can capture usability and accessibility issues that are not detected through only syntactic analysis of websites’ content. Finally, we proposed a Common User Profile format that can be used to compare and contrast accessibility systems and services, and to simulate and personalize interaction for users with different range of abilities. RESULTS AND CONCLUSIONS: After careful evaluation of two websites using the ten tools, we noted that, both websites lacked color contrast between background and foreground; lack of sign language alternatives; opening of pop-ups without proper warnings and so on. Further, results from comparative analysis of selected web accessibility tools noted that, there is no single tool that can be found ideal in all aspects. However, from our study, Utilitia Validator by Utilitia SP. z O.O was considered the most feasible tool. By rectifying and incorporating issues and alternate suggestions by simulation study and Common User Profile format respectively, developers can improve both websites making it accessible to maximum audience.","PeriodicalId":22201,"journal":{"name":"Technology and Disability","volume":" ","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3233/TAD-210329","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46588473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rolling resistance (RR) is one of the key forces that leads to increased propulsion forces and risk of injuries. OBJECTIVE: To better understand the factors contributing to RR, we iteratively designed, developed, and validated a drum-based testing machine and test method. METHODS: As part of the validation of the system, we tested and compared 4 manual wheelchair wheels under a range of conditions including camber, toe in/out, tire pressure, surfaces, and speed. A treadmill was employed to simulate flat ground RR. RESULTS: A machine was effectively designed, developed, and tested to measure RR. Tire type, surfaces, and toe were found to be the largest contributors to RR. Comparison of the drum-based system to flat ground revealed that an offset can be used to calculate overground RR from drum measurements. CONCLUSIONS: Ongoing work includes performing a comprehensive analysis of the degree to which each factor contributes to RR of commonly used casters and rear-wheels so that the wheelchair sector can work to reduce RR and the associated risk of repetitive strain injuries.","PeriodicalId":22201,"journal":{"name":"Technology and Disability","volume":"1 1","pages":"1-13"},"PeriodicalIF":0.5,"publicationDate":"2021-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3233/TAD-200285","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42242354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
